HEAD FOR POLO-CLUBS.

Patented May 14, 1912.

To all whom it may concern:

Be it known that I, ROBERT D. HAYES, a citizen of the United States,residing at New Haven, New Haven county, State of Connecticut, haveinvented certain new and useful Improvements in Heads for P010- Clubs,of which the following is a full, clear, and exact description.

My invention relates to polo clubs, particularly clubs for playing thegame of pony polo, and in which the side of the Ilgeald of the club isemployed for driving a The object of the invention is to improve theconstruction of the oluband provide a,

head of maximum strength, and yet so constructed as to secure greaterdriving force with a given blow than can be secured by the ordinary poloclub head as now constructed.

In the accompanying drawings, Figure 1 is a side elevation on a smallscale of a polo club complete. Fig. 2 is a relatively enlarged plan viewof the head with the shaft detached. Fig. 3 is a still further enlargedcross sectional view on the line 33 of Fig. 2.

1 represents the shaft or handle of a polo club at the lower end ofwhich is a head. The head is constructed of not less than three layersof laminations of wood, as indicated at 2, 3 and 4. The layers 2-4c formthe striking faces of the club head, by which I mean, the faces whichcontact with the ball. The lamination 3 constitutes the core. Whereasthe layers 2-4 aremade of a highly resistant material, preferably wood,the core 3 is made of a relatively springy material, preferably wood,which I find tends to augment the driving power of the club head. Theseveral layers which constitute the head may be secured together inanysuitable way, as by glue or cement. The outer laminations 24 shouldpreferably be made of a wood having a hard, dense grain, while the grainof the core should be relatively porous and springy.

5 represents an opening or hole which is designed to receive the end ofthe shaft or stick 1. As shown, this hole is preferably oblong or ovalin-cross section, the major axis thereof being in alinement with thecore 3. The end of the shaft 1, when fitted into this oblong hole andheld therein as by glue is very securely retained, and is guaranteedagainst rotation in the head, the strain which tends to rotate beingresisted by the cross sectional shape of the opening, rather than by theglue or cement, which latter, therefore, merely performs the function ofpreventing the shaft from being pulled out.

It will be observed that the hole 5 extends obliquely relatively to theaxis of the head, and that it is preferably formed wholly in the centrallamination or core 3. Since polo club heads should be of a sub.stantially standard size and weight, I find that said size and weightmay be maintained, even though the outer lamination or striking facesare made of heavier and more resistant material than the core, since, byselecting and using a material of sufficiently less weight for the core,compensation or due allowance for the excess weight of the outerlaminations may be made.

What I claim is:

1. In a polo club, a head comprising not less than three laminationssecured together lengthwise of said head, the interior lamination orlaminations being formed of relatively springy material as compared withthe external lamination or laminations and having a handle shaft securedthereto and extending therefrom.

2. In a polo club, a head comprising not less thanthree laminationssecured together lengthwise of said head, the interior lamination orlaminations being-formed of relatively springy material as compared withthe external lamination or laminations, and being centrally apertured toreceive a handle shaft, the material of the exterior lamination orlaminations being also more dense and heavier than the material of theinterior lamination or laminations.

3. In a polo club having a head composed of not less than threelaminations, the external lamination or laminations being of heaviermaterial than the interior lamination or laminations, said head having apassage obliquely arranged and centrally located between the endsthereof and entering the exposed edge of the internal lamination orlaminations.

4. In a polo club having a head composed of not less than threelaminations, the external lamination or laminations being of heaviermaterial than the interior lamination or laminations, said head having apassage obliquely arranged and centrally .10-

cated between the ends thereof and entering the exposed edge of theinternal lamination or laminations, the cross sectional outline of saidopening being elongated in the line of the club head.

5. In a polo club having a head composed of not less than threelaminations, the external. lamination or laminations being of heaviermaterial than the interior lamination or laminations, said head having apassage obliquely arranged and centrally located between the endsthereof and entering the exposed edge of the internal lamination orlaminations, the cross sectional outline of said opening being elongatedin the line of the club head, and a shaft fitted to said opening andsecured therein.

6. In a polo club, a laminated head including not less than threelaminations arranged longitudinally thereof, said head tapering from thecenter toward the ends, an oblique shaft passage extending through saidhead obliquely and between the outside laminations, the material of theinterior lamination or laminations being less dense than the material ofthe side faces or external lamination or laminations of said head.

7. In a polo club, a laminated head including not less than threelaminations arranged longitudinally thereof, said head tapering from thecenter toward the ends, an oblique shaft passage extending through saidhead obliquely and between the outside laminations, the material of theinterior lamination or 'laminations being less dense than the materialof the side faces or external lamination or laminations, the crosssectional shape of said shaft passage being elongated substantially inthe line of the axis of the head.
